What

check and lint reported missing_three_script (and would report missing_lottie_script) on a scene whose parent document already loads the library, so the only way to pass was to load it again inside the scene.

A sub-composition shares its parent's document at render time, so a library the parent loads is available to it. missing_gsap_script and the GSAP plugin rule already skip sub-compositions and <template> scenes; the Three.js and Lottie rules now follow the same rule through one helper in adapters.ts. A root composition with no library is still reported.

Why

Reported from 0.8.226: "a scene using a library loaded in the parent document should pass dependency detection; the checker required the library in the scene itself."

Test

New test, run for both rules: a <template> scene using THREE. or lottie.loadAnimation is not reported, whether or not it is flagged as a sub-composition. The existing tests that a root composition without the library is reported still pass. The whole lint package (1246 tests) passes 3 runs in a row.

fails without the fix: packages/lint/src/rules/adapters.test.ts › adapter rules › does not report missing_three_script in a scene, since the parent document loads the library

Approving at 6def8ed5. I found no blockers.

• Fails without the fix: I verified this. With adapters.ts reverted to the merge-base, both named cases fail (missing_three_script and missing_lottie_script). With the fix, the whole lint package passes: 23 files, 1246 tests.
• Same rule as GSAP: inheritsLibrariesFromHost uses the same condition as missing_gsap_script, missing_gsap_plugin and missing_timeline_registry: isSubComposition, or a source that starts with <template. Project lint passes isSubComposition: true for every compositions/*.html. A root composition is still reported.
• Non-blocking:
  • The same trade-off as GSAP applies. A scene that uses Three.js or Lottie is no longer flagged, even when the parent document doesn't load the library either. A later improvement could check, at the project level, whether the host loads the library a scene relies on.
  • The <template>/sub-composition condition now appears in four rules. A shared helper in context/utils would keep them in sync.

The gate passes.
Smoothness is reported in the artifact, not gated. A case fails only if it fails 2 of 3 runs.
